The Viper X II is ROKA’s next generation swimskin and the best they have ever made!

The Viper became the most popular swimskin at the IRONMAN World Championship in two short years for a reason. It was first out of the water on multiple occasions and the fastest overall swim. But how did they make the fastest, faster?
Improvements include integrated thermobonded "X" taping on the interior to provide strategic support, enhanced connection and power without restricting breathing or adding any drag to the ultrafast hydrophobic suit.

They made subtle refinements to sizing and several construction details for improved stretch and comfort in the armpits. ROKA took the same uncompromising, ground-up design approach based on years of competitive swimming and triathlon experience, and strategically incorporated all the latest advances in performance swimwear materials and construction. The Viper X features hidden innovation from our team's design research on the Maverick X project, and years of athlete testing and feedback.
The Viper X swimskin is USAT and WTC legal and continues to utilize two varieties of the same premium stretch-woven textile from Italy, a hydrophobic Teflon® coating, high-tech bonded seam construction with novel hidden stitch reinforcement, a low profile autolocking YKK zipper. It is strategically designed with a pattern and panel layout that liberates your arms while providing support where you need it. All of these little details add up to free speed on race day. The Viper X comes in black only, with “magma" graphics for men and “spark" graphics for women.

If you have a non-wetsuit race on your calendar, the ROKA Viper X offers the ultimate in swimskin performance. In 2015, almost 25% of the athletes at Kona wore Viper swimskins – more than any other brand. Get on board while stocks last.
